Lette/rs Patent No. 93,958, dated August 24, 1869.

IMPRQVEMNT IN coax-CUTTING MACHINE.

ThevSchedule referred to in these Letters Patent'an making part of thesame.

To all whom it may concern:

lBe it known that I, EDMUND A. Brunson, of the city, county, and Stateof New York, have invented a. new and useful Improvement in Cork-CuttingMachines; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to makeand use the same, reference being had to the accompanyingdrawing, forming part of this specification.

This invention'relates to new and useful improvements in machines forcutting corks, and consists mainly. in three principal parts, thel firstbeing the portion for shaping or rounding the corks from the squareblocks; secondly, the portion forA cutting thesquare blanks; and,thirdly, the portion rfor cutting veneers or thin pieces for variouspuiposes, as will be hereinafter more fully described.

In the accompanying sheets of drawing- Sheet I represents a top or planview of the machine, showing the position of the various parts, and

the manner of their arrangement.

Sheet II is an end elevation.

Similar letters of reference indicate corresponding parts.

A represents the frame, which isretangular in form, made of either wood0r metal, and of suitable size and strength.

B is the main shaft, supported transversely across the frame, upon theend of which is the main cutter G, by which the corks are rounded andtheveneers are put.

The cutter C is strengthened by a stiff collar, seen at C', 0n the mainshaft behind the cutter, to which thecutter is attached.

I) is another shaft across timeframe, with a cutter, E, upon its end,for cutting the raw corkinto square. blanks. f

This shaft is dliven'from the main shaft B by means of the belt F.

G isanother transverse inclined shaft, which is also driven by themainshaft B, by th'belt H.

Eis the cutter on the shaft D.

h isa gauge o n the table of the cutter E, where the cork is cut intoblanks or squares.

The mechanism for rounding the corks, or rather for holding the cork tothe main cutter, and revolving it while being rounded, is attached tothe adjustable frame I, Sheet II.

This frame is adjusted in height by means of the stop-screws J J, onwhich the frame is supported.

The square blankl of cork is placed between the disks 'i e', which arerevolved on separate shafts It l, by means of belts from the pulleys ZZ. f

The shaft k has no longitudinal motion, while the shaft k has, and isforced, by means of a weight, m,

toward the other shaft with sufficient 4power to hold the cork betweenthe disks 'i .i whilevbeing rounded.

The weight m is attached to the long end of a bent lever, which has itsfulcrum at the elbow, while the short end is connectedl with the shaftk.

The frame I has a forward and back motion given it bymeans of theball-'and-socket joints on the stop- 4 The 4short disk-shafts It lo arehung in adjustable boxes, and are rotated by means of belts on thepulleys l l, which extend down to pulleys on a parallel shaft beneath,not seen in the drawing.

This unseen shaft is driven from an upright shaft,

the top end of which is seen at o, and which is itselfv driven by thebelt P, from the main 4shaft B.

R is'a lever, which is attached to a horizontal shaft, seen in dottedlines on the frame I, which governs the position of the frame I, in itsmovements to and from the cutter C.

This is accomplished by means of vknuckle-joints S, Sheet II.

A The ends of the limbs T of the knuckle-joint are i lconnected with arod, a, supported by brackets on the frame A, in iront of the cutter O.

By raising and lowering the lever R, the knucklejoints are turned, andthe frame-I is moved to or from the cutter G, and at the same time thebelts which drivelthe disk-shafts (or k 7d) are tightened or loosened.Y, Sheet I, represents a sliding frame, to the inside of which the corkto be cut into veneers or thin pieces is placed, as seen at W, where thecork is seen in red color.

X X represent screws, by which the cork is fed up -to the cutterforbeing cut into veneers or thin pieces.

The piece revolves independently and separately from the cutter, andalways at a certain xed rate of speed, in proportion to the speed of thecutter. It is at all times entirely under the control of the operator,as in hand-cutting.

By this machine any-sized cork, in length 0r diameter, can be cnt.

wood, it is extremely difiicult to properly select and cut corks of thevarious sizes, by the present mode, without great waste of material. Bythe use of this machine a very great saving is eected. r

The frame I, being adjustable, so as to'prestmt the 'From the uneventhickness of corkpieee of cork to the knife for cutting any desiredtaper, and the pieee being directly under the eye of the op' erator,each blank is so eut as to make the most of it, or to avoid Waste.

If it is desired to eut eorks of a uniform size, a stop may be appliedfor limiting the forward movementof the frame I. f I do not confinemyself co the particular methods shown for Carrying out my invention, asregards the details, my object being to secure the three main featuresbefore mentioned.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-
